    Hello sir. Thank you for your reply. Actually my father is a printing machine mechanic. I am in UAE. Now he is working for komori sprint. He is not using camera phone and I have no photos. He is telling when taking screen from side to side there are lines. Not from tail to head.

    Hi sir:

    Normally, when this happen is the ball bearing in the cylinder, to due the normal wear in the ball bearing.

    Only the factory, has the tolerance, that they need for to replace, very Important!!

    However you must test all adjustment, from Ink Roller, Water, Pressure, and paralelism of cylinder.

    If there are ALL o.k proceed with the before indications above

    Sir,
    Now the problem solved by my father. He reset all the rollers one by one. Now print is perfect but one problem: ink roller is not automatically off. But he will rectify now. Sir I reached India. I will take photo and send once I finish quarantine

    Hi sir:

    The problem with the registration, can be too many factors, please review this:

    1) Lateral guide bad function, oscillators grippers, inferior guide

    2) humidity paper, to due recently fabrication .the humidity will be 55-60% to 18-20grades C

    3) Printing paper with the Fiber in Reverse direction.

    4)Out of register , in the sense of packaging of cylinders,, add or take out according.

    Merry Christmas.
